SASH-WEIGHT.

SPECIFICATION forming part of Letters Patent N 0. 752,235, datedFebruary 16, 1904. Application filed May 25, 1903. Serial No. 158,697.(No model.)

To all whom it may concerm.

Be it known that I, JOHN T. LEONARD, a citizen of the United States ofAmerica, and a resident of the borough of Bronx, New York city, andState of New York, have invented certain new and useful Improvements inSash- W'eights, of which the following is a specification.

My invention consists of improvements in window sash-weights whereby theadjustments for accurately balancing the sash and for application of theweights are simplified, as hereinafter described, reference being madeto the accompanying drawings, in which 7 Figure 1 is an elevation of twosections of a sash-weight constructed and coupled in accordance with myinvention. Fig. 2 is another.

elevation of the same in a view at right angles to the view of Fig. 1.Fig. 3 is an elevation in the same view as Fig. Qin a double arrangementfor heavy sashes. Fig. 4 is a vertical section of part of a window-frameand side elevation of part of a suspended weight, showing the facilityafforded by my improved construction for application and removal of theweights in use. Fig. 5isafront elevation of the apparatus represented inFig. 4.

I make the weights either in single arrangement, as shown in Fig. 2, orin double arrangement, as in Fig. 3, according as they are r to beapplied to light or heavy sashes, in

series of short sections or, preferably of cast 'metal formed with aprolongation 6, of each end of half the thickness of the intermediatebody part, said prolongationsbeing disposed on opposite sides of thesaid body part, respectively, the extremities cof said prolongationsbeing rounded to a radius of half the width of the body and theshoulders of the body part being recessed to the same radius, as at (Z,and said prolongations being centrally perforated at e for bolting thesections together in a flexible chain, the first link of which may beconnected to the sash-chain It, and then the successive links may beconnected together and inserted piece by piece through a short slot f inthe plate g, forming the bottom of the sash-groove it of thewindow-frame 6, thus enabling the application of the weight into'theweight-chamber Z and its removal therefrom more readily than when otherforms of sectional weights are used.

In Fig. 3 I represent the double arrangement of two single weights inone for larger and heavier windows, which is feasible by the endprolongation's of reduced thickness being on' opposite sides of the bodya, respectively, whereby they overlap, so as to connect in a chain ofuniform thickness, and the two series of pieces may be placed side byside, so that the prolongations of one end of the combined pieces areseparated by a space m, in which the prolongation of the other end ofthe same, as a, but of another pair of pieces, may enter and be securedby a joint-bolt 0 One of the said prolonged parts of each weight-pieceis countersunk for a taper screw-head, as q, and the other for a nut, aso,- for application of the. joint-bolts 0 without projections.

What I claim as my invention isl. The improvement in sectionalsashweights consisting of such weights constructed in series of sectionshaving overlapping end prolongations of opposite sides respectively,said prolongations axially perforated and pivot-bolted in a flexiblechain adapted to be inserted into the weight-space through a slot of nogreater length than the length of a weight-section.

2. The improvement in sectional sashweights consisting of such weightsconstructed in series of sections having overlapping end prolongationsof Opposite sides respectively, with rounded terminals and concaveshoulders, said prolongations axially perforated and pivot-bolted in aflexible chain, adapted to be inserted into the weight-space through aslot of no greater length than the length of a weight-section.

Signed at New York this 14th day of May,

JOHN T. LEONARD.
